The New York Times told readers that when Watson implied "that black Africans are less intelligent than whites, he hadn't a scientific leg to stand on."
I wish these assurances were true. They aren't. Tests do show an IQ deficit, not just for Africans relative to Europeans, but for Europeans relative to Asians. Economic and cultural theories have failed to explain most of the pattern, and there's strong preliminary evidence that part of it is genetic. It's time to prepare for the possibility that equality of intelligence, in the sense of racial averages on tests, will turn out not to be true.
